| 目的 探讨使用偏度-中位数-变异系数法(LMS法)建立并比较乌鲁木齐市7～18岁维吾尔族(维族)和汉族青少年超重、肥胖的体重指数(BMI)分类标准.方法 采用分层整群抽样方法,调查新疆乌鲁木齐市7～18岁维、汉族中小学生9146人,绘制两民族7～18岁青少年年龄别、性别BMI百分位曲线,确定18岁时分别通过国际肥胖工作组(IOTF)和中国肥胖问题工作组(WGOC)成年人超重、肥胖标准的特殊百分位数曲线,由此获得两民族7～18岁人群超重和肥胖的界值标准.结果 18岁时通过25及30 kg/m2的百分位曲线:维族男生为P94.46和P99.58,维族女生为P92.44和P99.64,汉族男生为P85.05和P97.26,汉族女生为P90.92和P99.03;通过24及28 kg/m2的百分位曲线维族男生为P90.54和P98.86,维族女生为P86.96和P98.77,汉族男生为P78.98和P94.72,汉族女生为P86.15和P97.56.结论 BMI分布具有民族特异性;对维族青少年超重、肥胖筛检时建议参考使用该研究标准. |

| Objective To construct and compare the body mass index (BMI cutoff points for defining overweight and obesity in school-age children and youths with Uygur and Han ethnic backgrounds in Xinjiang,China.Methods A total number of 9146 boys and girls in Urumqi,Xinjiang,aged 7-18 years,were recruited by stratifying and clustering sampling from April to June 2004.Demographic and anthropometric data,including body weight and standing height,were collected.Questionnaires and standard methods were used and BMI was calculated by weight/height2.BMI centile curves with age were drawn according to gender and ethnicity,using LMS software (Tim cole and Huiqi Pan which were making the centile curves passing through 25 kg/m2 and 30 kg/m2,and 24 kg/m2 and 28 kg/m2 at age of 18 for overweight and obesity respectively.Results The age and sex specific BMI centile curves were drawn for children with Uygur and Han ethnicities.Data showed that BMI increased with age.The centile of BMI curves,P94.46 and P99.58 for Uygur boys,P92.44 and P99.64 for Uygur girls,P85.05 and P97.26 for Han boys,P90.92 and P99.03 for Han girls,which passing through 9.5 kg/m2 and 30 kg/m2 by IOTF recommendation at age 18,were constructed.Under the basis of WGOC recommendation,the points that passing through 24 kg/m~2 and 28 kg/m2 at age 18 were P90.54 and P98.86 for uygur boys,P86.96 and P98.77 for uygur girls,P78.98 and P94.72 for Han boys,P86.15 and P97.56 for Han girls.The BMI cutoff points for defining overweight and obesity were suggested.Conclusion To the best of our knowledge,the present study established the BMI cutoff points for Uygur ethnic school-aged children and youths for identifying overweight and obesity.There was ethnic difference in the BMI distribution with age.We recommended using the BMI cutoff points proposed by the current study to identify those overweight and obese children in Urumqi. |
